## What it is
ThingsGateway is an open-source, cross-platform industrial IoT edge gateway built on .NET 8 for high-performance data acquisition, edge processing, and protocol conversion. It uses a plugin-based architecture supporting protocols like Modbus, OPC UA, MQTT, and S7, with a Blazor web UI for configuration, monitoring, and forwarding data to MQTT, databases, Kafka, and APIs.

## Use cases
- collect data from Modbus TCP/RTU PLCs and publish it over MQTT
- build an industrial IoT edge gateway for factory floor devices
- convert between industrial protocols like S7, OPC UA, and MQTT
- forward PLC register data to a database, Kafka, or web API
- run edge-side data filtering and preprocessing before sending to the cloud
- monitor and manage multiple gateway instances from a web dashboard
- acquire data from Siemens S7 and OPC UA devices on Linux or Windows

## When to choose
- you need a self-hosted, open-source industrial data acquisition gateway with a web UI
- you work with common industrial protocols (Modbus, OPC UA, MQTT, S7) and need edge processing
- you want a plugin-based .NET gateway you can extend with custom C# scripts or drivers
- you need cross-platform deployment on industrial PCs or edge servers running Windows or Linux

## When to avoid
- you need proprietary PLC protocols like FINS, CIP/EtherNet/IP, or SECS without purchasing PRO plugins
- you require a lightweight headless library rather than a full gateway application with a management UI
- you cannot accept the community edition requirement to keep the ThingsGateway logo and author attribution
- your project is not .NET-based and you need a gateway in another language or runtime
